The technical field of the present invention is the technical field of agricultural machinery.

Background technology

The sprinkler of the sprinkler of known a period of time, the type includes the turbine being mounted in nozzle, which has Opening, air-flow reach the production external, carrying is quantitatively sprayed by the nozzle in the influence area of air-flow is arranged by the opening Product.

In general, nozzle is located in the path of air-flow, to which the product sprayed by them is directly entrained by the flow of air；However, In some equipment, nozzle is moved far from air-flow, but projects product to be incorporated into the air-flow.

The nozzle that the saying for being located at the influence area of air-flow about nozzle means in the path of air-flow be it is such, i.e., one It flows through nozzle just product is attached in air-flow denier, and the nozzle far from air-flow movement can project product, to be tied It closes in air-flow.

In this manner, product (being typically plant health product) is transported on the crop that it must be administered by air-flow.

In these sprinklers, air-flow typically at most is adjusted for each agrotype, in entire spraying time Air-flow and Product dispenser are constant, and any variation is engaged with the engine of towing vehicle due to air generator, is passed through The revolution of engine is increased or decreased to change rotary speed, changes air flow outlet in an uncontrolled fashion.

It is obvious that product is wasted, and because on the one hand even also continuing to spray in the intermediate region of not plant, and it is another On the one hand lacking leads to generate the excessive power of undesirable drift to the control of output gas flow or the shortage of the product is caused to be applied The insufficient power added, this leads to part Crop damage or new processing is needed to apply in turn.

In order to overcome aforesaid drawbacks, spray control system has been developed.The presence or not of some of them detection phytomass In the presence of stopping sprinkling in the case of no plant.

British patent GB2214047 is related to a kind of including sprinkler there are detector, in the feelings of not phytomass There is no sprinklings under condition, and further include for adjusting the amount of institute's dispensing according to the speed of towing vehicle to realize uniform spray The device spilt；The patent does not describe the device of the air-flow for controlling the engine independently of towing vehicle.

Spanish patent ES2047997 describes a kind of equipment of type discussed above, can ensure there is constant work( The air-flow of rate but regardless of fan drive device how.For this purpose, it includes air flowing meter and is used to change at its source The device of air flowing.Option as its consideration comprising the fin in fan suction areas, for changing suction cross section Device or device for changing fan pitch.However, the patent does not describe the device of combination.

Existing patent document further relates to the sprinkler with larger the degree of automation and for promotes spray line System, in patent US5098018, it discloses a kind of for adjusting fan blade and the system of conical cavity, for along entire Whole length of spray arm keep sprinkling air flow constant.

There are many patents for the system for being related to the leaf position for adjusting fan, wherein most of belong to aviation and start Machine field.Example include such as DE19600660, DE4331825 old document or such as ES2356490, JP2006057627 or The nearest document of JPS5888498.

Same applicant holds pervious record, and Spanish Utility Model U200301196 is related to a kind of sprinkler, such The sprinkler of type includes the turbine in nozzle, and the nozzle is last towards the distribution being arranged in air stream outlet channel by the air-flow of generation End is oriented to, and is had the characteristic that the nozzle has the linear motion towards or away from end, so as to constriction or is widened gas channel And change the air-flow of output.The record does not discuss the combination of other components for changing air outlet slit speed.

The test of progress shows to reach external each air-flow for being intended to carrying product, turbine and be open all there are one Best coordination configuration.

Turbo arrangement is understood to obtain its adaptability of particular airflow, and the configuration that is open is construed as adjusting The size of the opening of external air capacity is reached per unit time.

The behavior of air-flow outside reaching is not gradual or proportional, does not follow simple arithmetic pattern yet.Thing In reality, for the given air-flow generated by turbine, larger opening is not always related to proportional larger output flow, for Given opening size, proportional increase or reduction output flow will not be led to by changing the air-flow generated by turbine.

There are several factors to influence exit flow, only the coordination control of the air-flow and opening size that are generated by turbine is just permitted Perhaps correct air-flow is obtained in the most efficient manner.

It is hitherto known, it is realized without sprinkler (some of which combines some cited patents) by being proposed The level of energy and products perfection that the theme of invention is provided.
